Qualcomm is definitely the number one mobile SoC manufacturer in the world. Many manufacturers implement company's Snapdragon processor units in their devices, for a reason, Qualcomm has been making great mobile SoCs for years now. The competition is getting stronger, MediaTek is growing, and there are other names that are worth mentioning like Samsung's Exynos chips, Huawei's HiSilicon Kirin units and LG's new Odin processors. The three latter brands are not exactly a competition per se, considering they manufacture units only for their respective devices at the moment, but could become a threat in the future.
Anyhow, Qualcomm has recently announced that over 60 upcoming flagships in 2015 will be powered by their latest Snapdragon 810 SoCs. Everyone thought that the Galaxy S6 will be one of them, that is logical, Samsung's flagship smartphones were powered by Qualcomm's Snapdragon units for… well, forever, ever since the first Galaxy S handset. Then some reports came in saying that it might not be the case, after which it was reported that Qualcomm has lots a major client in 2015. Now everything points to the fact that the Galaxy S6 won't be powered by the Snapdragon 810, but Samsung's very own Exynos chip (7420 model). A number of previous Galaxy S and Galaxy Note devices were powered by both of these chips, Samsung was releasing two versions of these devices, but that won't be the case anymore it seems.
The reason behind all of this? Well, Samsung wants to be less dependent on Qualcomm. I don't know if you're aware of this, but Qualcomm's Snapdragon SoC's offer complete single-chip solutions, which basically means they include everything on there, including an on-board modem, while that's not the case with Samsung's Exynos chips. This would give Samsung more options as far as different components go, because they wouldn't have to use Qualcomm's solutions for a processor, GPU, modem, etc. That's at least one way to look at it, though according to new reports, Samsung is getting ready to mass produce a single-chip solutions of their own in Q4 2015. They already pushed some single-chip solutions out there, but not for their high-end devices. The company is basically preparing all-in-one SoC solutions for their smartphones, so they won't exactly need the help of Snapdragon anymore I guess.
Either way you look at this, we're talking about two SoC manufacturers here, and what Samsung is doing makes all the sense in the world. Why would they include someone else's SoCs in their handset when they can use their own? Truth be said, Samsung did have lots of issues with their Exynos chips in the past, but it seems like those are gone now. We'll see how things go from here, though according to this report, they're planning to reduce their usage of Snapdragon SoCs. Let us know what you think in the comments, would it bother you if Samsung Galaxy S6 (for example) wouldn't include a Snapdragon SoC on the inside?
